Abstract

Three ustilaginomycetous anamorphic strains were isolated from flowers of in mangrove forests of Taiwan. Phylogenetic analyses based on the combined sequences of internal transcribed spacer 1 (ITS1)-5.8S-ITS2 and the D1/D2 domain of the large-subunit (LSU) rDNA indicated that the closest recognized species was . The results of a DNA–DNA hybridization experiment and the physiological characteristics showed that the three strains represent a novel species within the genus . The name sp. nov. is proposed, with FIRDI 007 (=BCRC 23165 =CBS 11676) as the type strain. In addition, based on phenotypic characteristics and the phylogenetic analyses of the combined sequences of the ITS region and D1/D2 domain of the LSU rDNA, was clustered with the genus . A new combination, comb. nov. (type strain LM418 =DSM 18755 =ATCC MYA-4092 =NRRL Y-48466 =CBS 10858 =BCRC 23177), is proposed.
